As I am an osm beginner, when I encounter an error message, I am not 
able to understand if it will have bad consequences or not.

This is the error message :
svgo worker: `svgo` not found; please provide proper binary or disable 
this worker (--no-svgo argument or `:svgo => false` through options)

The only reference to svgo is the line 'svgo:' in the 
config/image_optim.yml file, following other parameters configured to 
false (e.g. jpegtran: false).

But when I try to set it to false ('svgo: false' in image_optim.yml), 
the next time I run trails server, it fails :
/var/lib/gems/2.0.0/gems/psych-2.1.1/lib/psych.rb:379:in `parse': 
(/data/openstreetmap-website/config/image_optim.yml): mapping values are 
not allowed in this context at line 12 column 18 (Psych::SyntaxError)

So chances are the best choice is to have the 'svgo not found' message 
at the console and keep the osm web site available.

If I properly read the CONFIGURE file, an alternative could be osm2pgsql.

But I already used it to build a tile server as described here :
in the "Loading data into your server" item.

It has filled postgis tables planet_osm_xxx and not the postgres tables 
described in rails port/database schema.

So, would be osm2pgsql be smart enough to fill both schemas ? Do you 
advice another way to fill in the data ?

And last, if we only fill the rails port tables (for the web site), is 
there a trick to automatically populate postgis tables too (for the tile 
server) ?
